GEARING- FOR ENSILAGE-MACHINES.

Application filed February 2, 1914.

To all whom it may concern:

Be it known that I, NORTON M. BROWN, a citizen of the United States, anda resident of the city of Aurora, county of Kane, and State of Illinois,have invented certain new and useful Improvements in Gearing forEnsilage-Machines, of which the following is a specification.

My invention relates to improvements in gearing for ensilage machinesand has for its object the production of gearing operatively connectingthe driving shaft of the machine with the feeding elements thereofwhereby the rotation of said feeding elements may be reversed, whendesired, with ease.

A further object is the production of gearing as mentioned which will besimple and economical and efiicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which- Figure 1 isa fragmentary sectional view of the feeding and cutting mechanism of anensilage machine equipped with gearing em-- bodying my invention, andFig. 2 is a section taken on line wa2 of Fig. 1.

Referring now to the drawing 1 designates the power shaft of theensilage machine which is mounted in suitable bearings provided in thehousing or casing 2 thereof. Arranged in the housing 2 is the cutterhead 3 of the machine which is operatively connected for driving by thepower shaft 1. The grain or stalks which it is desired to out are fed tothe cutter 3 by means of rotable feeding elements 4 and 5, the former ofwhich is mounted upon a shaft 6 and the latter upon a shaft 7 whichshafts are rotatably mounted in suitable bearings provided in thehousing 2. Arranged between the shafts 6 and 7 with its respective endsmounted in bearings provided in the sides of housing 2 is acounter-shaft 8 which is operatively connected with the power shaft 1 bymeans of a sprocket chain 9 which passes around sprocket wheels 10 and11 provided respectively upon shafts l and 8.

Driving of the feeding elements 4 and 5 is obtained through the mediumof shaft 8,

one end of the latter being provided with a Specification of LettersPatent.

gear 12 which is fixed thereto. Said gear 12 meshes with a gear 13 whichis loosely and shiftably mounted upon shaft 6. Arranged at oppositesides of gear 13 upon the shaft 6 are gears 14 and 15, the former beingfixed to said shaft 6 and the latter being loosely mounted upon saidshaft. The gear 13 is provided at opposite sides with clutch teeth 16and 17 adapted, upon shifting of said gear, to interlock respectivelywith clutch teeth 18 and 19 provided upon gears 14 and 15 as clearlyshown in Fig. 1. With this arrangement it will be seen that operativeconnection between gear 13 and either of the gears 14 and 15 may beeffected by simply shifting said gear 13 to engage the clutch teeththereof with the clutch teeth of the gear with which operativeconnection is desired. A suitable shifting fork 13 cooperates with thegear 13 for effecting the desired shifting thereof as mentioned. Thegear 14 is operatively connected through the medium of an idler gear 20loosely mounted upon the shaft 8 with a gear 21 which is fixed to theshaft 7. The gear 15 meshes with a gear 22 which is also fixed to shaft7 In the operation of the machine positive or forward movement of thefeeding elements 4 and 5 is effected when gear 13 is in operativeconnection with the gear 14, such I connection being made throughinterlocking of clutch teeth 16 and 18. The gear 13 being in constantmesh with the gear 12 and being therefore constantly rotated duringmovement of shaft 8, upon interlocking of clutch teeth 16 and 18, thegear 14 and hence the shaft 6 to which said gear is fixed, will becorrespondingly rotated, effecting forward or positive movement of thefeeding element 4. The gear 14 being in constant connection throughidler gear 20 with the gear 521 which is fixed t0 shaft 7, said shaftand hence the feeding element 5 will also be positively rotated in thisarrangement of the gears. When it is desired to reverse the movement ofsaid feeding elements it is only necessary to shift the gear 13 so as todisengage clutch teeth 16 and 18 and interlock clutch teeth 17 and 19.When this is done the gear 15 will be rotated in unison with the gear13. Such rotation of said gear 15 will cause rotation of gear 22 whichin turn will cause rotation of shaft 7 and hence the feeding element 5,the rotation of the atter in this case i g reverse or a vice notinfrequently results in the prevention of great damage to the machineorinjury to the operator.

lVhile I have illustrated and described the preferred form ofconstruction forcarrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. 1, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:
